The Hoya 39 Duto Glass Diffusion Filter is a diffusion filter that helps to create a soft focus quality while maintaining sharp focus in the center of the image. Fine concentric lines are etched on the surface of the filter to produce this effect. This filter is ideal for use in portrait and commercial photography situations.
The Duto filter incorporates Hoya's Standard filter coating to help improve light transmission while reducing reflections and flare.
